DeltaTox® II is a simple, rapid, extremely responsive, portable water quality test system. Designed for acute toxicity screening and adenosine triphosphate (ATP) testing, DeltaTox® II uses bioluminescence technology to screen for contamination in instances of drinking water emergencies and chemical spills into water systems. DeltaTox® II is the portable toxicity analyzer used with the Microtox® technology

Description

The DeltaTox® II instrument has a combined detection capability that provides a very sensitive and rapid test to detect two of the most probable classes of agents, pathogens and toxic chemicals that may accidently or intentionally contaminate drinking water or wastewater. DeltaTox® II’s acute toxicity and ATP detection capabilities make it the ideal instrument for rapidly and accurately assessing if the quality of drinking water, from the source to the tap, has been affected by an incident.

DeltaTox® II is designed for use in any sample location throughout the water distribution or industrial waste water system. It is particularly suited to remote sites such as reservoirs, storage tanks, ocean or lake going vessels or in any hard to reach place.

Chemical contamination of drinking water and wastewater

DeltaTox® II is the portable version of the industry-leading Microtox® Model 500 (M500) laboratory analyzer. The DeltaTox® II test is fast, simple to conduct, uses small sample sizes and is very cost effective. Results correlate well with those from other toxicity bioassays such as fish, daphnia and shrimp. DeltaTox® II is used extensively in the measurement of toxicity of “fit for use” water and wastewater treatment effluent. It is also used as an early screening tool for relative toxicity as part of a test battery.

DeltaTox® II test systems are uniquely suited for drinking water surveillance where supplies are monitored regularly and at strategic points. It can quickly reveal any changes in the level of toxicity of drinking water making it the ideal solution for major events. Microtox® has been deployed at every Summer Olympics since Los Angeles in 1984.

DeltaTox® II can rapidly estimate the microbial concentration of a drinking water sample to a level of 100 cfu/mL without additional filtration or incubation steps. The data is available in minutes and is highly correlated with standard heterotrophic plate count methods.

DeltaTox® II is extremely responsive and has been designed for use in a wide variety of applications where it is crucial to rapidly determine the biomass of a sample.

Features

Test sensitive to more than 2,700 different simple and complex chemicals

<20% coefficient of variation for B-Tox and Q-Tox mode testing
Sensitivity and Range: The analyser can detect photon counts from 0 to 60 million

Process explained

The DeltaTox® II test system uses a strain of naturally occurring luminescent bacterial called Vibrio fischeri to provide acute toxicity detection. Exposure to a toxic substance causes disruption of the respiratory process of the bacteria resulting in reduced light output.

DeltaTox® II is extremely responsive and has been designed for use in a wide variety of applications where it is crucial to rapidly determine the biomass of a sample. All organisms contain ATP as their main energy source but it is the amount of ATP in a sample that is directly proportional to the biomass of the sample.

ATP reacts with luciferin/luciferase, the enzyme system present in firefly tails, to produce light. In the reaction, each molecule of ATP produces one photon of light; the light output of this reaction can be accurately measured using the very sensitive DeltaTox® II instrument.
